This paper describes the characterisation of a synthetic workload for performance evaluation of a new system before replacing a legacy system. The workload is used by CAPPLES, a capacity planning and performance analysis method for the migration of legacy systems. Typical workload characterisation problems are anticipated and discussed. Further, guidelines to characterise a CAPPLES workload for...

We present a new method for stable coalition formation in a context of dynamic tasks and selfish autonomous agents with unpredictable availability. Our method is based on a mechanism of alliances and recommendations to ease stable coalition formation despite the dynamism of the agents and of the tasks. An experimental performance evaluation of our method is also proposed to highlight the proper...

background: emphasis on revise and provide new methods of evaluation in medical colleges are widely increasing. evaluation methods based on clinical practice and students’ performance appraisement in health care system and in medical student is introduced as an effective method in some studies. methods: the aim of this study was to consider the usefulness of a new method to evaluate the medical...

IMUTUS (Interactive Music Tuition System) is a EU project that aims to develop a practising environment for the recorder, combining new technologies and new approaches for music learning. Automatic analysis and evaluation of student performances play a central role in the student-system interaction. The performance evaluation module identifies typical performance errors, and provides feedback t...

This paper investigates the Multi-band OFDM (MB-OFDM) based physical (PHY) layer proposal for IEEE 802.15.3a working group on short-range high data-rate Ultra-wide-Band (UWB) communications. An overview of the MB-OFDM PHY layer architecture with its various parameters is presented and the optimal choice of critical parameters is discussed. Next, we derive the theoretical un-coded Bit Error Rate...

Several prototypes for predicting the short-term market reaction to news based on text mining techniques have been developed. However, no detailed comparison of the systems and their performances is available thus far. This paper describes the main systems developed and presents a framework for comparing the approaches. The prototypes differ in the text mining methods applied and the data sets ...
